- Crosley air compressor tag.
It says, "Pressure Vacuum Machine. This machine is licensed for use in connection with enhancing blood circulation in and on the head only". What the hell was this thing used for? I've been using it for years to air up tires. ///update---it is from a Crosley Xervac. A piece of quackery that had the compressor hooked to a helmet, it was supposed to stimulate hair growth.
